for \(\Xi _{c}^{0}\rightarrow \Xi ^{-}e^{+}\nu _{e}\) , where \(\tau (\Xi _{c}^{+})=(456\pm 5)\) 
fs and \(\tau (\Xi _{c}^{0})=(153\pm 6)\)  fs have been used [1]}.
The uncertainties come from those of the form factors. Considering
the lifetime of \(\Xi _{c}^{0}\)  changing from around 112 fs in PDG2018-2019
[2]} to around 153 fs in PDG2020 [1]}, in Table REF ,
only the decay width is compared with those from other works. It can
be seen that, most theoretical calculations are larger than the most
recent experimental data from Belle and our result is consistent with
the current world average, that of ALICE and that of Lattice QCD.
